High-volume resistance training reduces postprandial lipaemia in postmenopausal women

Abstract

The aim of this study was to compare the effects of 11 weeks of low-volume resistance training (LVRT) and high-volume resistance training (HVRT) on muscle strength, muscle thickness (MT), and postprandial lipaemia (PPL) in postmenopausal women. Thirty-six healthy and untrained postmenopausal women (age, 58.9 ± 5.8 years; 68.6 ± 10.3 kg; and BMI, 26.9 ± 4.8 kg · m(-2)) participated in resistance training 3× per week for 11 weeks (HVRT = 12; LVRT = 13; and control group = 11). Biochemical variables, both pretraining and post-training, were evaluated 16 h after the administration of an oral fat tolerance test (OFTT) and metabolic variable during [energy expenditure (EE)] and after training session [excess postexercise oxygen consumption (EPOC)]. Muscle strength (1 RM) and MT were also calculated, and no significant differences were observed between the groups for PPL (mmol · L(-1) per 5 h) as measured by glucose, high-density lipoprotein, low-density lipoprotein, and total cholesterol. EE total (EE + EPOC; 6.12 ± 1.21 MJ vs. 2.26 ± 0.85 MJ), resting fat oxidation (5.52 ± 1.69 g · h(-1) vs. 4.11 ± 1.12 g · h(-1)); MT (vastus medialis, 21.4 ± 1.8 mm vs. 18.4 ± 1.2 mm and vastus lateralis 22.3 ± 1.2 mm vs. 20.8 ± 1.3 mm); triacylglycerol (TAG) 0, 1, 2, 4; and 5 h after OFTT, TAG area under the curve (AUC) (5.79 ± 0.42 vs. 7.78 ± 0.68), and incremental AUC (-46.21 ± 14.42% vs. 7.78 ± 4.68%) were all significantly different post-training for HVRT versus LVRT, respectively (P < 0.05). The results of this investigation suggest that HVRT reduces PPL in postmenopausal women.

Resistance Training Volume Enhances Muscle Hypertrophy, but Not Strength in Postmenopausal Women: A Randomized Controlled Trial

“…Many of the studies have failed to show a difference in muscle hypertrophy between the routines (12,17,32,34), but not all (10,31). Regarding this, the effect sizes (from pre-intervention to postintervention) of these studies (when analyzed collectively) (10,12,17,31,32,34) have shown a higher effect to HV-RT ( d = 0.8) than LV-RT ( d = 0.5) (the effect size was calculated by the authors of the current study). Thus, a low effect size (Δ d = 0.3) may be observed between one-set and 3-set routines in muscle hypertrophy.…”

Exercise to Lower Postprandial Lipemia: Why, When, What and How

“…Therefore, any effect of exercise training on PPL should be considered a chronic effect only if it is observed at least two days after the last exercise session. In this sense, findings of studies that investigated the effect of training on PPL by administering a test meal less than two days or on undisclosed time after the last exercise session [118][119][120][121][122] cannot be considered as reflecting chronic exercise effects.…”

Fasted exercise does not improve postprandial lipemia responses to different meals in lean and obese subjects: A crossover, randomized clinical trial

“…For determination of the energy expenditure for the control, isocaloric, and caloric deficit protocols subjects used the same equipment, and seated on the cycle ergometer for 5 min before starting the protocols. Total energy expenditure was calculated as the sum of the absolute measured VO 2 (l. minÀ1 ) for each minute during protocols (discarding the initial 5 min), multiplied by 3.5 (to obtain the metabolic equivalents), which were multiplied by 5.0 (kcal.L À1 ) [32]. Post-exercise oxygen consumption was not considered for the determination of the caloric content of the meal.…”
